A method, computer system, and a computer program product for migrating a service from one container to another container is provided. The present invention may include obtaining a first group of requests that are accessing a service launched in a first container instance and a second group of requests that are waiting for accessing the service. The present invention may also include generating a migrated service in a second container instance by migrating the service from the first container instance to the second container instance based on the obtained first and second groups of requests. The present invention may further include directing the second group of requests to the migrated service in the second container instance.

Container based service management

A method, computer program product, and a computer system, to store information related to changed data in response to a transaction with a first database of the on-line system requested during a planned period and data in the first database changed by the transaction. In response to a planned event a back-up system with a second database is switched to set up a new connection and a new transaction with the second database, wherein the second database is backup of the first database. The on-line system prevents setting up a new connection to the on-line system and prevents conducting a new transaction with the first database, sends information related to the changed data from the on-line system to the back-up system, and switches to the back-up system for a new connection and for a new transaction. The on-line system synchronizes data between the first database and the second database.

The invention relates to a method for preparing silica modified by a silane coupling agent. The method comprises the following steps: preparing a kind of coupling agent sol solution by mixing the solvent, water, catalyst and coupling agent; uniformly dispersing silica into the sol solution by means of ultrasonic dispersion or shear dispersion to achieve a turbid solution with uniform dispersion and ideal particle size; and then stirring the turbid solution at a constant speed to make the coupling agent sol reacting with silica to prepare highly hydrophobic silica modified by the coupling agent through controlling the temperature and reaction time. The coupling agent sol solution is obtained by a sol-gel process and silica is uniformly dispersed in the coupling agent sol solution through combined action of various dynamic means to ensure the sufficient reaction between silica and coupling agent, thus to obtain silica modified by the coupling agent.
